As I mentioned a bunch of pages back, I obtained an old Sunfish rig, including sail, for a song. The only problem was the mast was bent down near the deck end. Bummer. But, the original Sunfish mast was a hybrid: four feet of aluminum tube topped with six feed of wooden mast. Well, my bent mast has more than four feet of straight tube at the top, so that's what I'm doing.
The original Sunfish spars were derived from the wooden Sailfish, just made a bit longer. Kent Lewis documented the Sailfish spars here if you're curious:

Before starting on the mast, I did a couple of trials at sparmaking on a 3-foot long 2x4 cut in half lengthwise. Conveniently, the resulting 1-1/2 inch square pieces are the same dimensions as the boom and gaff that I'll be making so it seemed like a good test. The tests were successful and good practice, so I set out to make the wood portion of the mast.
I began with a 2-1/4" square blank of laminated Douglas Fir, which you can see below. It's marked out to have a slight taper as well as a sheave (pulley) for the halyard embedded at the top, just like the original.
In sparmaking, the drill is to knock off all the corners in an organized fashion, such that you turn a square into an octagon. Knock off the corners of the octagon and you get a 16-sided polygon. Wash, rinse, repeat. Here's the first corner planed off, developing the octagon:
You can see the mortise that I chopped out for the sheave near the top of the mast. That's the first mortise I have created ever. There was not a 3/8-inch mortise chisel to be had anywhere in North America, so I made do. It's adequate, but I'm not in danger of putting any fine furniture makers out of business.
Little old mast maker.
